Take a deep breath when you step into Au Kouign Amman—the smell of butter (and lots of it) has filled this minuscule shopfront in the Plateau for over 35 years. The production kitchen for kouign amman and the house croissant is just feet away from the counter, and you can watch the pâtissiers laminate the layers of this Bretagne specialty that’s so popular, lines sometimes go out the door. There’s a few tiny tables here if you want to eat one of these freshly made dense, flaky orbs on the spot.
